MAX2870ETJ+TG2Z

Overview

The MAX2870ETJ+TG2Z is a fractional and integer-N synthesizer with an integrated voltage-controlled oscillator (VCO), manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a frequency range of 23.5 MHz to 6 GHz, supporting general-purpose RF applications. The device is housed in a 32-WFQFN exposed pad package, specifically a 32-TQFN (5x5) configuration, designed for surface-mount installation. This component integrates phase-locked loop functionality to provide stable frequency generation for wireless systems.

Feature Summary

• Integrates fractional and integer-N synthesis capabilities with a built-in VCO
• Supports wide frequency coverage from 23.5 MHz to 6 GHz
• Designed for general-purpose RF signal generation applications

Applications

• Wireless communication systems requiring frequency synthesis
• General-purpose RF signal generation circuits
• Integrated transceiver front-end modules

Procurement Notes

Verify component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm availability of alternative packages or direct replacements via Analog Devices documentation. Ensure compliance with RoHS3 specifications and check for any product change notices affecting supply chain continuity. Validate packaging type against current inventory requirements.

Selection Notes

Select this component when a combined synthesizer and VCO solution is required for frequencies up to 6 GHz. Consider the 32-TQFN package constraints for PCB layout and thermal management. Evaluate integration benefits over discrete PLL and VCO designs to reduce board space. Verify compatibility with system reference clock requirements and output power needs for the specific application bandwidth.

Part Context

The MAX2870 belongs to the Maxim Integrated family of RF synthesizers, now part of Analog Devices Inc. following the acquisition. It serves as a compact solution for generating precise frequencies in wireless infrastructure and portable devices. The ETJ suffix indicates the specific temperature grade and package variant within the broader MAX2870 product line.
